Many people stop along Interstate 70 at Genesee Park in the summer to view the herd of buffalo that lives in that area. (Read more about the buffalo herd here.)
But sometimes, buffalo-viewers get a little too close or even decide to crawl over the wildlife fencing to get a better photograph or view of the beautiful bison.
The following video, taped in Yellowstone National Park, serves as a reminder that, while buffalo seem mostly peaceful, they can get agitated and become a danger. (And remember, when a buffalo charges, a wire fence like the one at Genesee is not always going to stop it.)
